Hi, Sorry, I don't know how to reply to a post using the digest. But my question is if 100Hz or 10KHz are available from a GPS unit, where do they come from? Does that mean there is a 10MHz oscillator somewhere on the pcb that is just divided down?
If so, then adding another PLL loop to control an external 10MHz crystal will just add additional noise, jitter, variable phase offset, etc. If there is already a 10MHz oscillator, wouldn't it be simpler to add a buffer like paralleled sections of a 74AC04 to the source, and drive a 50 ohm coax directly?
